Gen.1:1 In the beginning the father created the heavens and the earth. Gen.1:26 Let Us create man in our image. In the image of God, HE created them male and female. Revelation 4:4
Around the throne were twenty-four thrones, and on the thrones I saw twenty-four elders sitting, clothed in white robes; and they had crowns of gold on their heads.

Revelation 4:10
the twenty-four elders fall down before Him who sits on the throne and worship Him who lives forever and ever, and cast their crowns before the throne, saying:

Revelation 5:8
[ Worthy Is the Lamb ] Now when He had taken the scroll, the four living creatures and the twenty-four elders fell down before the Lamb, each having a harp, and golden bowls full of incense, which are the prayers of the saints.

Revelation 5:14
Then the four living creatures said, “Amen!” And the twenty-four elders fell down and worshiped Him who lives forever and ever. (Only the father has lived for ever and ever, Jesus died)

Revelation 11:16
And the twenty-four elders who sat before God on their thrones fell on their faces and worshiped God,

Revelation 19:4
And the twenty-four elders and the four living creatures fell down and worshiped God who sat on the throne, saying, “Amen! Alleluia!”

Ps.103:20 Bless Adonai, you angels of his, you mighty warriors who obey his word, who carry out his orders!

Matt. 5:34  But I say to you, do not swear at all: neither by heaven, for it is God’s throne; Jesus tells us that, God sits on His throne.

Mark 10:5 5 And Jesus (speaking) answered and said to them, “Because of the hardness of your heart HE (father) wrote you this precept. 6 But from the beginning of the creation, God ‘made them male and female. Jesus confirms who is God and that the father created man as Jesus states above… 

The “Us” from Gen.1:26 is implicit, but we learn from the above scriptures that Jesus confirms the father was the creator and that Heaven is His Throne and that the 24 elders likely are the “US.”
